• the respective pivot mechanism is designed to move the screen device depending on a control signal between a stowed position in which the screen device is stowed in a housing curved along an arc and a use position in which the screen device protrudes at least partially from the housing move.
• a flexible screen device in the context of the invention is to be understood as a flexible screen device. In other words, the screen device can be bent as a whole.
• a flexible display surface or display layer of such a screen device can be implemented, for example, by a film and / or film layer arrangement and therefore be flexible.
• a flexible carrier layer for such a screen device can have a structural and / or material or material flexibility.
• Pixel-based display contents are display contents made up of individual pixels, which can be displayed, for example, on an OLED-based (OLED - organic light emitting diode) or TOLED-based (transparent OLED) display surface.
• EP 1 637 387 A1 shows a display device for a vehicle, comprising a flexible display.
• the display device also has a housing and a stabilizing mechanism designed as a concertina gate for the display.
• the disadvantage here is that the elements of the concertina arm in a stowed position must inevitably protrude beyond the edge of the display, which leads to an increased space requirement.
• the display device described has a flat screen image, which is made of flexible material.
• the screen When moving into a viewing position, the screen is curved and transported over a roller. In a free-standing viewing position, it is provided that the screen assumes a predetermined shape without the flexibility of the screen being restricted.
• the disadvantage of guiding over a role is that when designing a new model with different dimensions, a respective radius of curvature of the screen can only be varied with great constructive effort, since all parts connected to the role have to be re-dimensioned.
• transport on a roller inevitably leads to increased wear and tear on the rear of the screen.
• DE 10 2014 016 323 A1 also describes a display device for a motor vehicle with a flexible display device and an adjustment device.
• the display device is designed to be moved from a stowed position into a use position. Here it is bent, so that a display surface of the display device is bent in the use position.
• the curved display surface has the disadvantage that the respective display contents are displayed in a distorted manner in case of doubt and the display surface cannot be clearly seen by all vehicle occupants.
• the invention is based on the object of providing a display device which makes it possible to display surface sizes of different sizes. in which the display device should have little space requirement and should be able to be adapted to changing space conditions without great structural effort.
• the object is achieved by the subjects of the independent patent claims.
• Advantageous further developments of the invention are described by the dependent claims, the following description and the figures.
• the invention provides a display device for displaying pixel-based display content.
• the device comprises a flexible screen device and at least one pivot mechanism.
• the at least one swivel mechanism is designed to move the screen device between a stowed position and a use position as a function of a control signal.
• the screen device is stowed in the stowed position bent along a Kreisbo gene in a housing.
• the screen device protrudes at least partially from the housing.
• the screen device in the stowed position, the screen device is stowed away from the outside in the housing, and in the use position at least a partial area of the screen device is visible because it protrudes from the housing.
• the screen device In the stowed position, the screen device therefore has a curvature.
• the curvature can follow an external shape of the housing, which can be constant or non-uniform.
• the screen device has one, two or generally more pivot mechanisms.
• the use of several swivel mechanisms is suitable for enabling a large and / or heavy screen device to be moved.
• the invention is characterized in that the at least one pivot mechanism each has a motor and a pivot arm.
• a motor can for example be an electric motor that is connected to an external energy supply.
• the swivel arm is rich with an Endbe, so with an end area, rotatable at a foot area the screen device and mounted pivotably about an axis of rotation with an opposite end region.
• the swivel arm can be elongated or rod-shaped and have two end regions which are opposite one another. The two end regions can be the two ends of the pivot arm.
• One end of the swivel arm is thus arranged rotatably on a predominantlybe rich of the screen device.
• one end of the pivot arm is arranged in such an area of the screen device which, in the use position in which the screen device protrudes at least partially from the housing as described, is closest to the housing or still remains in the housing.
• the rotatable mounting enables the swivel arm end to roll or rotate at the foot area of the screen device.
• the opposite end of the swivel arm is rotatably mounted about an axis of rotation, for example on the motor or on a gearbox that couples the swivel arm to the motor.
• the storage can therefore be implemented directly, for example on a shaft of the motor, or indirectly, for example via a Zahnradan arrangement of a transmission.
• the swivel arm is designed to receive a respective torque from the motor and thereby move the foot area along the circular arc, the radius of which corresponds to a length of the swivel arm, and thereby alternately move the screen device (i.e. depending on the swivel direction of the swivel arm) to slide (extend) into the use position and pull (retract) into the stowed position along one direction of movement.
• a torque of the motor is transmitted to the swivel arm, whereby this executes a swivel movement.
• the torque of the motor is thereby transferred to the foot area of the screen device as thrust or tensile force.
• the pivot mechanism provided with the motor and pivot arm has the advantage that it is possible to react to different installation space situations by replacing a single component, namely the pivot arm.
• the length of the swivel arm directly defines the radius of the circular arc for the stowage position.
• the pivot mechanism provided has the advantage that the screen device only has to be connected to the pivot arm at certain points. There is no full-surface stress on the rear of the screen device, as would be done, for example, when guided over a roller.
• the invention also has the advantage that the screen device can be bent along the arc and thus stowed in a space-saving manner.
• the invention also includes embodiments which result in additional advantages.
• the display device has a housing.
• the at least one pivot mechanism is arranged according to an advantageous embodiment inside the housing and designed to move the screen device from the stowed position steplessly depending on the control signal in at least one Eisenpo position and hold it there.
• the screen device can assume and hold any number or a predetermined number of steps between the stowed position and the fully or fully extended position of use. There are therefore several exit stages or exit positions, i.e. two or more than two. This has the advantage that a certain screen size can be produced or set as required.
• the Ge housing can completely or partially enclose the at least one pivot mechanism and the screen device.
• the screen device has a carrier layer and a display layer which are connected to one another to form a flexible layer composite.
• the carrier layer is preferably provided with notches on its rear side.
• the carrier layer preferably has notches on a surface facing away from the display layer.
• the carrier layer is designed to be curved, the notched surface having a smaller radius of curvature in a curved position than the surface connected to the display layer and opposite the notched surface.
• the carrier layer is preferably provided with a structure on the rear.
• the structure can have notches and / or ribs.
• the notches and / or ribs advantageously run in a direction perpendicular to a displacement direction along the rear side of the carrier layer.
• the movement direction is the direction in which the screen device is pushed and pulled in order to move into the use or stowed position.
• the notches and / or ribs result in the advantage of structural flexibility or pliability of the carrier layer, the material from which the carrier layer is formed can in principle have an inherent stiffness.
• the inherent rigidity of the carrier layer advantageously makes it possible for the carrier layer to prevent the entire screen device from tipping over or waves in the position of use without additional stabilizing means being necessary.
• connection between the carrier layer and the display layer can, for example, be implemented by an adhesive layer.
• An adhesive layer offers the advantage that an adhesive has damping properties and can absorb a shear force, for example to compensate for or absorb a relative movement between the carrier layer and the display layer.
• the connection between the carrier layer and the display layer can, however, also take place in any other, expedient manner. It can be provided that the screen device is held mechanically pretensioned in a bent position in the storage position and is mechanically relaxed and straight or flat in the use position. In other words, the screen device is fixed in a bent position within the housing by a force acting on the screen device from outside.
• the force acting from the outside can be exerted on the screen device, for example, through the housing wall and / or a roller and / or lateral guide rails.
• this force no longer acts and the screen device can assume a straight or flat shape.
• the screen device is straightened or erected automatically in that the screen device is automatically freed from the force holding it in the bent position when it leaves the housing. Unaffected by this, provision can also be made for additional guide elements to be attached to the housing output, which support the straightening or erecting of the screen device.
• the screen device has a touch-sensitive sensor layer.
• the display layer of the screen device has a touch-sensitive sensor layer which is arranged on the display layer.
• the screen device can therefore generally be a touch screen (touch screen).
• the screen device is preferably a touch screen, whereby by means of the touch-sensitive sensor layer, which is also designed to be flexible, touches on the screen device can be detected and converted into corresponding control signals.
• the display device has at least one stabilization element that is variable in length or adjustable in length.
• the stabilizing element is in a first end area with connected to the screen device and mounted rotatably about an axis of rotation in an opposite second end region.
• the stabilizing element is designed to adapt its length to the respective positions when the screen device is moved between the stowed position and the position of use.
• the stabilization element is designed to support the screen device against a force acting along the axis of rotation. In other words, moving the screen device between the stowed position and the position of use has the result that the length-variable stabilizing element is automatically pulled out and retracted again alternately.
• the stabilizing element is preferably arranged with one end on a face area of the screen device arranged opposite the foot area of the screen device, that is to say on the upper edge of the screen device.
• the stabilizing element of variable length is preferably designed as a passive element. As a passive element, it is moved with the movement of the screen device.
• the length-variable stabilization element is designed as an active element which can actively support the movement of the screen device by means of its own drive. This can be advantageous in the case of a particularly large and / or heavy screen device.
• the stabilization element has the advantage that the screen device is stabilized against a pressure force acting on a screen upper surface and can thus be used as a touchscreen user interface.
• the stabilizing element is guided in the front region of the screen device in an elongated hole running perpendicularly or at an angle to the above-described displacement direction of the screen device.
• the first end region of the stabilizing element can slide along the elongated hole running perpendicularly or obliquely to the direction of displacement of the screen device.
